アス型のものに比べ、切断時に発生する切粉の排出効果
に優れている。[0003] This segment type diamond cutting whetstone has an effect of discharging chips generated at the time of cutting, compared with a continuous type in which a whetstone layer is fixed to the entire outer periphery of the substrate by the action of a slit provided between the segment chips. Is excellent.
【０００４】しかしながらこのようなセグメントタイプ
のものと雖も、完全な切粉の排出は困難であり、さらに
切粉の排出効果に優れたものの出現が望まれている。[0004] Despite the segment type, however, it is difficult to completely discharge chips, and it is desired to develop a chip having an excellent chip discharging effect.

おいては、切断時に多量の摩擦熱が発生するが、これは
特にセグメントチップの中間領域において顕著に発生
し、切断砥石の焼け付き、また切断能力の低下等の原因
となっている。[0005] In such a diamond cutting wheel, a large amount of frictional heat is generated at the time of cutting. This heat is remarkably generated particularly in an intermediate region of the segment chip, causing seizure of the cutting wheel and a decrease in cutting ability. And so on.

Japanese Patent No. 5742 discloses a cutting whetstone in which a concave portion is formed on the outer peripheral surface of a segment chip, whereby the effect of discharging chips can be improved to some extent.
【０００７】しかしながら、同公報に記載された凹部

ることはできない。However, the concave portion described in the above publication has a rectangular cross section in which the bottom surface and the side surface of the concave portion are orthogonal to each other, and chips are likely to remain at corners where the bottom surface and the side surface intersect, which is effective. It is difficult to discharge fine chips. Further, with such a structure, it is impossible to reduce the temperature rise at the center of the segment chip.

固着力を保持することが困難となる。This problem can be dealt with, for example, by increasing the number of slits by dividing the segment chips into smaller pieces or by increasing the slit width. However, when the slit width is increased, the segment chips are intermittently attached to the workpiece during cutting. It may cause vibration. In addition, when the number of slits is increased, the length of each segment chip is shortened, the bonding area between the chip and the iron substrate is reduced, and it is difficult to maintain a safe fixing force.

Japanese Patent Publication No. 172560 proposes that the concave portions formed on both ends of the outer peripheral surface of the segment chip are trapezoidal concave portions that expand outward, and that a concave portion for supplying cooling water is formed at a substantially intermediate position inside the segment chip. . According to such a concave structure, chips at the time of cutting can be easily discharged to the outside along the tapered surface of the trapezoid, and the effect of discharging chips can be improved.

する場合がある。However, according to the subsequent research, it has been found that the chips still remain at the corners where the bottom and side surfaces of the trapezoidal recess formed in the segment chip intersect and are not completely discharged. did. Also, when cutting hard concrete, stress may be concentrated at corners where the bottom and side surfaces of the trapezoidal concave portion intersect, and cracks may occur to cause breakage.
【００１１】そこで、本発明において解決すべき課題
は、先に提案した台形状凹部における切粉の排出効果を
さらに高めると共に、強度を向上させることにある。Therefore, the problem to be solved in the present invention is to further enhance the effect of discharging chips from the previously proposed trapezoidal concave portion and to improve the strength.

外広がりの台形状凹部を形成したダイヤモンド切断砥石
において、この台形状凹部の底面隅部に曲率半径が１．
０〜２．５ｍｍの曲面部を形成したことを特徴とする。According to the present invention, a segment chip is fixed to the outer periphery of a disc-shaped substrate, and an outer spread base which is opened in the radial direction of the disc-shaped substrate is provided on the outer peripheral surface of the segment chip. In the diamond cutting whetstone having the concave shape, the radius of curvature is 1. at the bottom corner of the trapezoidal concave portion.
A curved surface portion of 0 to 2.5 mm is formed.

る傾向にある。Here, if the radius of the curved portion is less than 1.0 mm, the chip discharging effect and the strength of the segment chip are not much different from those of the conventional product. When the radius is in the range of 1.0 to 2.5 mm, the chip discharging effect and the strength of the segment chip are improved as the radius increases, but the radius of the curved surface portion is 2.5 mm.
If the radius exceeds 2.5 mm, the chip discharge effect becomes constant, and the strength of the segment chip tends to decrease if the radius exceeds 2.5 mm.

A curved surface of 5 mm can be formed.

る。Here, it is desirable that the total length of the bottom of the opening of the trapezoidal concave portion on the front side is within 25% of the length of the segment chip, and the depth of the concave portion is within 70% of the height of the segment chip. If the total length of the opening exceeds 25%, the disadvantage of the segment tip portion occupying the outer periphery of the blade, that is, the reduction of the blade life due to the reduction in the so-called tip ratio, exceeds the effect of suppressing chip wear by improving the chip discharging ability. If the depth of the concave portion exceeds 70%, the strength of the segment chip divided by the concave portion decreases.
